Daytime SX LUT Measurement, etc. 20180502

17:08 Trying to understand focus problem
  • focus = 7.47, H band, N3.75, Spot at 1016, 1028
  • focus = 4.8, Do not see any source on N3.75 camera

17:47 Background
  • LUCI1 247, TN 174753

17:52 Closed Loop
  • bin 4, 400 Hz, 36 modes
  • Gain 0.6, 0.1, 0.1
  • Hex -1.31, 1.55, 7.44, 149.9, -209.9
  • bayside -75.5, -51.1, 49
  • bayside stages off
  • TT LUT On
  • Instrument Rotator at 330 (On rotator grid point)
  • LUCI1, clear/HKSpec, 2.5 sec, Flexure LUT On
  • Note: 45 el TT LUT was a copy of 60. Installed new below.

17:54 Collect data.
  • Start at El = 90, Move manually by 2 degrees, collect TN and LUCI1 image
  • First LUCI1 248, TN 175551, El = 90 (only collect 1 TN, Will collect 3 after this)
    • Oops, second set at 88.5.
    • third at 86
  • Take data down to 76 then 75
  • Now take data at 5 degree intervals
  • El = 60, 281, 182645

18:32 Close loop with bin 1, 990 Hz to get rid of high order shapes

18:33 Collect data
  • Start at El=60, 282, 183322
  • Stop at El=45, 293, 184452

18:51 Move to El=30 in closed loop, bin 4
  • 30 El flat 20180502_30el_bin4
  • 30 El flat 20180502_30el_bin1 (good flat)
  • Rotator to 450
  • back to bin 4

19:02 El=30 TT LUT calibration data
  • bin 4, 400 Hz, 36 modes
  • Bayside stages powered on and holding (current)
  • TT LUT Off
  • LUCI1, clear/HKSpec, 2.5 sec, Flexure LUT On
  • First Rot = 450, LUCI1 2, TN 190650
    • Note: LUCI1 41, TN 192921 increased TT gain from 0.6 to 1.0
    • Note: AdSec Arbitrator died when I increased gain, near 1.0. Time 192919 (or close)
  • Last Rot = 90 LUCI1 59, 194310

19:46 El=30 more calibration data, -90 to 450
  • First LUCI1 60, TN 194519 (TT gain set to 0.85, a bit of blinking)
  • Last LUCI1 117 (?), TN 201751

20:48 Installed TT LUT with 45 correct elevation (above 45 was copy of 60)
  • TT LUT On
  • Bayside Stages Off
  • Rot = 345 (off rotation grid)
  • First El = 45, LUCI1 119, TN 205145 (Move manually by 2 degrees, collect TN and LUCI1 image)
  • Last El = 60, LUCI1 145, TN 211309

21:14 Rot = 345, El=65 to 90
  • First LUCI1 146, TN 211636
  • Last LUCI1 163, TN 213920

21:39 Close Loop bin1 to get good flat
  • Back to bin 4, collect data
  • LUCI 164->166, TN 214653 -> 214743

22:30 Tracking star. Moving in Az and El
  • Start with El=80, Transit at 82.2
  • Rotator start at 215
  • Start with Az = 132
  • TT LUT On
  • Bayside Stages off
  • First LUCI1 167, TN 223003
  • Last LUCI1 217, TN 232244

  • Dark 218, 232902
